alloy coating was produced on the brass substrate by laser-induction hybrid cladding (LIHC). The microstructure and property of the coating were investigated. The results show that during LIHC when... identified as ε-Cu phase precipitate inside the spherical α-Fe particles. As a result, the average microhardness of coating is about 2.8 times higher than that of the brass substrate. Key words: Cu-Fe......

搅拌摩擦焊与手工电弧焊接头电化学腐蚀性能研究 王文礼1,尹娟1,王文1,张小龙1,王快社1,郭韡1 (1.西安建筑科技大学,陕西,西安,710055) 摘要:通过测定H65铜合金搅拌摩擦焊接头和手工电弧焊接头在3.5%NaCl溶液中的开路电位和极化曲线,研究其电化学腐蚀性能.结果表明,搅拌摩擦焊接头的抗腐蚀性能优于手工电弧焊接头.搅拌摩擦焊接头微观组织的细化,均匀化和致密化降低了晶界和晶粒在电化学上的不均匀性.手工电弧焊接头脱锌层和基体界面处产生的拉应力对抗腐蚀性能有较大影响. 关键词:H65黄铜; 搅拌摩擦焊; 手工电弧焊; 开路电位; 极化曲线; H65 brass alloy; friction stir welding; manual arc welding; open potential; polarization curve; [全文内容正在添加中] ......
